ROAD- CART.

SPECIFICATION forming part of Letters Patent No.,271,223, dated January 30, 1883.

Application filed November 2,1882. (No model.) I

To all whom it may concern:

Be it known that I, THEODORE F. OONKLIN,

. a citizen of the United States, residing at Lil Fond du Lac, in the county of Fond duLac and State of Wisconsin, have invented a new and useful Road-Gart, of which the following is a specification.

My invention relates to improvements in road-carts in which oscillating body-loops Operate in conjunction withspiral'springs and an equalizing tie-bar with the arms of the springs; and the objects of my improvement are, first, to neutralize the horizontal jerking action of the body of the vehicle; second, to provide an easy vertical spring movement; third, to equalize the weight on the springs by automatically varying the leverage of the arms; and, lastly, to reduce the cost ot'material atul construction in the springs of the vehicle, spiral springs being the cheapest as well as the most flexible for the purposes above stated. 1 attain these objects by the mechanism illustrated in the'a-ccompanying drawing, which is a perspective view of my invention with outline sketch of body and parts of the vehicle of which it forms a part.

The spiral springs A are hung to the axle 3 of the vehicle by means of a bolt, d, through the core of the spring supported by clips 0 e, fastened to the axle. The long arm A of the spring produced from the top ot'the spiral extends backward and upward a convenient length, and moves with reference to the weight a: backward and downward. The short end or arm a of the spring rests against the forward face of the axle, y.

The body-loop B is formed of a bar bent in i right angles at points opposite the outer cor- 11ers or edges of the body or seat of the vehicle w, producing the arms or braces BB, which are slightly curved, and extend downward and backward from the cart-body or seat 00 to the ends of the spring-arms A,and to which ends they are hinged or pivoted. This body-loop B B is attached to the rear end of the cart-body m by straps, staples, eyebolts, or similar device, forming boxes b b, in which, through its bearings, the body-loop B turns or oscillates with the motion of theweight 00.

The "equalizing-bar Ois laid across and affixed to the arms B B a proper distance from their respective ends, and (aside from its use as a tie) when extra weight of passengers and roughness of" the road unusually depress the springs it meets and res s upon the springarms A at points .inside of the hinge a, and thus shortens the leverage and largely stiffens and strengthens the support of the springs.

The front of the cart-body is attached to the. shafts or cross-bar g by means of any loop device playing loosely thereon. I show this as letteredf in the drawing, but claim no novelty or particular device for this front body-loop.

1 claim as my invention and desire to secure by Letters Patent--- 1. The combination, in a road-cart, of the spiral springs A A, attached to the axle y, of bolt d, and clipsE E, with the body-loop B B, turning or oscillating in boxes I) b, affixed to and supporting the cart-body or weight at, substantially as described.

2. The bar 0, tying the braces B B, and automatically impinging upon the portion of the spring arm A intermediate the springeoil A and hinged joint a, substantially as shown, for the purpose specified.

3. The combination, in a road-cart, of the Oscillatingbody-loop or braces B B B, the spiral springs A A, the equalizing-bar O, and the cartbody anaxle y. and front body-loop, f, substantially as and for the purpose set forth.
